No user serviceable parts inside. Refer servicing to qualified service personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated ‘dangerous voltage’ within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. Class II product This equipment is a Class II or double insulated electrical appliance. It has been designed in such a way that it does not require a safety connection to electrical earth (‘ground’ in the U.S.). Warning Mains plug/appliance coupler is used to disconnect device and it shall remain readily operable. CAUTION: In Canada and the USA, to prevent electric shock, match the wide blade of the plug to the wide slot in the socket and insert the plug fully into the socket. Many of these items are common sense precautions but, for your own safety and to ensure that you do not damage the unit, we recommend that you read them. Important safety instructions This product is designed and manufactured to meet strict quality and safety standards. However, you should be aware of the following installation and operation precautions. 1.

E-13 E-3 welcome… English Contents Arcam’s A18 Integrated Amplifier provides class-leading sound quality. overview With a torrodial power supply, acoustically damped chassis and very low levels of noise and distortion, the A18 reproduces music with all its original authority and detail. Drawing on the many years of amplifier design experience at Arcam, the A18 uses the best quality components and engineering practice to produce a product that will give many years of musical pleasure and reliable service. ������� ���� ���� The A18 Integrated Amplifier is designed to produce a level of performance that will truly bring music to life. phO N O ������ ����� ������� ��������� ���� E-4 ��� �� ���� 20 ����� ��� ������������������������ ������ ��� ��� �� ��� ������ ����� English Placing the unit < Place the amplifier on a level, firm surface, avoiding direct sunlight and sources of heat or damp. < Do not place the A18 on top of a power amplifier or other source of heat. < Do not place the amplifier in an enclosed space such as a bookcase or closed cabinet unless there is good provision for ventilation. The A18 is designed to run warm during normal operation. < Do not place any other component or item on top of the amplifier as this may obstruct airflow around the heat-sink, causing the amplifier to run hot. (The unit placed on top of the amplifier would become hot, too.) < Make sure the remote-control receiver to the right of the front panel display is unobstructed, otherwise this will impair the use of the remotecontrol. < Do not place your record deck on top of this unit. Record decks are very sensitive to the noise generated by mains power supplies which will be heard as a background ‘hum’ if the record deck is too close. Power Interconnect cables The amplifier is supplied with a moulded mains plug already fitted to the lead. Check that the plug supplied fits your supply – should you require a new mains lead, please contact your Arcam dealer. We recommend the use of high-quality screened cables that are designed for the particular application. Other cables will have different impedance characteristics that will degrade the performance of your system (for example, do not use cabling intended for video use to carry audio signals). All cables should be kept as short as is practically possible. If your mains supply voltage or mains plug is different, please contact your Arcam dealer immediately Push the IEC plug end of the power cable into the socket on the back of the amplifier, making sure that it is pushed in firmly. Plug the other end of the cable into your mains socket and, if necessary, switch the socket on. It is good practice when connecting your equipment to make sure that the mains power-supply cabling is kept as far away as possible from your audio cables. Failure to do so may result in unwanted noise in the audio signals. E-5 A18 connections Speaker terminals Phono earth terminal See page 8 for information on connecting loudspeakers. For connecting your turntable earth lead, if required. Note that this terminal must not be used as a safety earth. Power inlet Connect the correct mains cable here. Aux input Analogue 3.5mm stereo jack socket, intended for connecting a portable MP3 player. ������������������������ ��������� ������� ������ ����� ���� ����������� ����� ���� � � � � � � � � ��� ��� ����������� �� ��� ��� �� ��� ��� ��� ����� �� ����� ���� ��� �� ������ ����� �������������� Voltage select Pre-amplifier connection Ensure that the voltage selected matches your local power supply. This socket is only used if you are using the A18 as a pre-amp, for example, when using the A18 in conjunction with a P38 in a bi-amplified system. See page 8 for more information. Audio connections Phones The labels above the connectors give suggested audio inputs, although any suitable device may be connected to the line-level inputs. (Note, however, that the name of the input shown on the front-panel display cannot be changed.) 3.5mm stereo jack socket, intended for use with a set of headphones. DVD, SAT, TUNER and CD are all line-level inputs. The phono (MM) input has different characteristics – see page 12 for the specification. In addition to the line level inputs, the AV and PVR connectors both have line level outputs for use in recording from other sources. See page 7 for more information. Note Please read the ‘Placing the unit’, ‘Power’ and ‘Interconnect cables’ sections on page 5 before connecting up your A18 integrated amplifier! E-6 English Pre-amplifier connection Audio inputs Recording loops Phono input PRE OUT Although the inputs are labelled for specific devices, all have the same characteristics and each may be used with any line-level product. The exception is the Phono (MM) input (see page 12 for the specification). The A18 is equipped with two recording loops: AV and PVR. These are for use with recording devices – such as a CD recorder, DAT recorder, cassette recorder, VCR, PVR, etc. The AV outputs may have any of the input connectors assigned to them for recording purposes. The phono inputs provide a pre-amplification stage to treat the low-voltage output from a moving magnet cartridge (input specifications are given on page 12). If you have already an external phono amplifier that you wish to use, connect its output to one of the line-level inputs. To use your A18 as a dedicated pre-amplifier, or as part of a bi-amp’ed system, connect the PRE OUT sockets to the input sockets of your power amplifier. AV IN Intended for the analogue outputs from general audiovisual equipment, such as a VCR, digital TV/satellite receiver, or Nicam tuner. AV OUT Connect these output sockets to the input sockets of your recording device (usually labelled RECORD or in). To record from a particular source, press the appropriate source button (for example, TUNER), then press AV. Any source selected immediately before AV is routed to the AV OUT connectors for recording purposes and is shown on the front panel (e.g. RC TUNER). PVR IN Intended for the analogue outputs from a Personal Video Recorder, or similar device. DVD Intended for the analogue outputs from a DVD-player. SAT PVR OUT The PVR Out also has the source selected immediately before AV routed to it, unless that source is PVR In, in which case PVR Out is muted. As with AV Out, changing to another source will change the signal that is sent to PVR Out. For connection to a satellite TV receiver or cable box. TUNER Intended for the analogue outputs from an FM, AM or DAB radio tuner. CD Intended for the analogue outputs from a CD player. AUX This is a 3.5mm analogue input on the front panel intended for use with devices such as MP3 players. To connect an MP3 player (or other portable audio device) you will need a 3.5mm to 3.5mm cable connected between the AUX input and the headphone socket of the device. E-7 Single wiring loudspeakers Single wiring is the conventional wiring method of running a single cable per channel between the amplifier and the speaker; this is the easiest technique. Notes on making speaker connections Similarly, connect the negative terminal of the amplifier (coloured black and labelled with R–) to the negative terminal of your speaker. Repeat the process for the left speaker, using the amplifier terminals labelled +L and L–. If each speaker has more than one pair of connecting terminals, use the terminals labelled LF or ‘Low Frequency’ for each speaker. < Do not make any connections to any amplifier while it is switched on. We recommend that your amplifier is completely disconnected from the mains supply before starting. < Before switching your amplifier(s) on for the first time after connecting to speakers, please check all connections thoroughly. Ensure that bare wires or cables are not touching each other or the amplifier’s chassis (which could cause short circuits), and that you have connected positive (+) to positive and negative (–) to negative. Be sure to check the wiring for both the amplifier and the speaker. < After making connections: switch the amplifier(s) on, select a source signal, then gradually increase the volume to the required listening level. < If you are unsure as to how your system should be connected, or need advice on bi-amping, please contact your Arcam dealer who will be happy to help you. If your speakers support bi-wiring, then there is a strip of conductive metal on the speakers connecting the lowfrequency terminals to those for the higher-frequencies; this must not be removed in a single-wired system. Connect the positive terminal of the right speaker connection on the amplifier (coloured red and labelled +R) to the positive terminal of your right speaker. ��������� � � � � � � � � ������ An A18 connected to speakers using single wiring Bi-amping Note that the strip of metal on the speakers connecting the lower terminals to the upper terminals must be removed. Failure to do so will result in damage to both amplifiers, which will not normally be covered under warranty. Bi-amping is the separation of the amplification of lowand high-frequency signals over two amplifiers. Bi-amping requires the use of two amplifiers per channel. Normally, your A18 is used to drive the highfrequency (treble) speakers, with a P38 used for the lower (bass) frequencies. ��������� � � � � � � Connect your A18 to the speakers as described for single wiring, with the exception that the A18 should be connected to the speaker terminals labelled HF or ‘High Frequency’. Then connect the power amplifier (an Arcam P38 for example) to the LF or ‘Low Frequency’ terminals, as in the diagram. A pair of audio interconnect cables are also required to connect the pre-amp outputs of the A18 to the power amp inputs of the P38. � � ������� ��������� � � � ������ � An A18 and P38 connected to speakers using bi‑amping E-8 ���� ���� remote control The CR10 is pre-programmed for use with the A18 as well as Arcam CD players (such as CD17). ����� - ��������� ���� ��� Amplifier commands ��� Vol – The CR10 requires a clear line of sight to the front panel display of A18 to ensure reliable operation.

Listening using speakers The A18 allows you to customise the balance, bass and treble levels of the amplifier to fit your system. Adjustments can be made either on the front panel or by using the CR10 remote control. Click the corresponding button to view the current setting, then use the control knob on the front panel (or VOL +/– buttons on the CR10) to adjust. The A18, in combination with a power amplifier, can be used to drive the front left and right speakers of a surround-sound system, when fed from a multi-channel processor. The volume of the entire system may then be controlled using the processor. The power light (next to the ‘A18 Integrated Amplifier’ text) indicates the state of the amplifier. The power LED is green and ON if the power is connected and the unit is turned ON. Display The front panel Display button (or DISP on the remote control) changes the display brightness between ‘on’, ‘dimmed’ and ‘off ’. If the A18 is powered off with the display brightness set to ‘off ’, the display resumes to ‘dimmed’ when the unit is powered on again. Selecting an audio source The audio source may be selected from the front panel (Phono, Aux, CD, Tuner, SAT, DVD, PVR or AV), or the remote control (DVD, SAT, AV, TUN, AUX, PVR, CD or PHO). In each case, the source is selected from the input sockets with the corresponding name. Use the control knob to change the volume. Turn the knob clockwise to increase the volume, anti-clockwise to reduce it. Listening using headphones The headphones socket (Phones) accepts headphones with an impedance rating between 8Ω and 2kΩ, fitted with a 3.5mm stereo jack plug. The pre-amp outputs and speakers are muted when headphones are plugged in. The headphones socket is always active, unless output has been muted. Muting output The output of the A18 can be silenced by pressing mute on the front panel (or - on the remote control). Press mute/- for a second time (or change the volume) to cancel mute. Balance This setting allows you to increase the volume of one channel (left or right) relative to the other. Altering the balance (from L9 to R9, via the neutral value 0) may help to restore the stereo image for an off-centre listening position. Bass This setting allows you to increase or decrease the level of low frequency elements in the sound within the range +7 to -7. Treble This setting allows you to increase or decrease the level of high frequency elements in the sound within the range +7 to -7. Direct mode This is a ‘tone defeat’ setting which ignores any Bass and Treble trim values. Press DRCT (Direct) on the remote control to toggle this setting; ‘DIRECT’ is lit on the display when Direct mode is active. E-10 While in Processor mode, you can feed the sound from the processor into AV in and set the ‘Proc mode volume’ of the A18 to match the amplifiers that drive your other loudspeakers. Set this ‘Proc mode volume’ using the VOL+ and VOL– buttons on the remote. The last set value of ‘Proc mode volume’ is remembered whenever Processor mode is selected. Processor mode may be toggled on and off (when AV is selected as the source) by using the front panel processor mode button or PROC on the remote. ‘PROC’ remains lit on the display while Processor mode is active. If you are having trouble with your amplifier, check the following items. No sound Check the following: < The A18 amplifier is powered up and switched on. < The amplifier is not muted (i.e. Mute is not shown on the display panel). < The selected source is generating audio (e.g., if CD is selected, then the CD is playing). < The AV input is selected on the A18 instead of the expected source. If there is no sound because the AV input is selected, press the correct source button on the front panel or remote control. < The speaker outputs are connected on the A18 (or on the power amplifier, in the case of a bi-amping arrangement). Recording an audio source The A18 allows you to record and monitor the sound from any connected source. The back panel AV Out or PVR OUT sockets can be connected to the input sockets of your recording device (these are usually labelled RECORD or in). The two recording loops have a similar function to each other, but are not exactly the same in operation. Sound cuts-out unexpectedly If the temperature of the internal heatsink rises above a safe level, then a thermal cut-out inside the amplifier operates to protect the unit and the protection system temporarily removes power to the speakers. The system will reset itself as the heatsink cools down. < With two pairs of low-impedance speakers connected (6Ω or less), overloads are more likely. Overloading the amplifier may cause it to shut down because of overheating. < Note that, due to the high output voltage from a CD player, it is possible to drive your amplifier at full power even though the volume is not set at maximum. To record from a particular source, press the appropriate source button (for example, TUNER), then press AV. Any source selected immediately before AV is routed to the AV OUT connectors for recording purposes and is shown on the front panel (e.g. RC TUNER). The PVR Out also has the source selected immediately before AV routed to it, unless that source is PVR In, in which case PVR Out is muted. As with AV Out, changing to another source will change the signal that is sent to PVR Out.
